JBXFD1G04MSSDSMR Equivalent & Substitute Parts

Part Overview

The JBXFD1G04MSSDSMR is a 4-position circular connector plug manufactured by Souriau-Sunbank by Eaton. This connector features male pins with solder cup termination, gold-plated mating contacts, and a shielded design rated for 10A at 900V. The connector operates across an industrial temperature range of -40°C to 125°C and is housed in a brass shell with chrome over nickel finish. The part is Active status and ROHS3 compliant.

Substitute parts are necessary when the primary manufacturer part is unavailable, when alternative sourcing reduces lead times, or when equivalent performance specifications from alternative manufacturers meet application requirements.

Substitute Part Grouping Explanation

Substitution of the JBXFD1G04MSSDSMR is determined by the following critical parameters:

Primary Substitution Criteria:

Connector type: Plug with male pins
Position count: 4 positions
Termination method: Solder cup
Fastening mechanism: Push-Pull
Contact finish: Gold plating on mating surfaces
Current capacity: 10A minimum
Shielding: Shielded configuration
Flammability compliance: UL94 V-0

Secondary Compatibility Factors:

Shell material: Brass construction
Insert material: Polyetheretherketone (PEEK)
Regulatory compliance: ROHS3 and REACH Unaffected status
Ingress protection: IP40 or higher

Substitute parts from LEMO and PEI-Genesis meet these core electrical and mechanical requirements. Variations in cable opening dimensions, operating temperature ranges, and shell finish do not preclude substitution when the primary electrical and mechanical parameters align.

Engineering Selection Recommendations

Direct Substitutes (Male Pin Configuration):

The LEMO FGG.1B.304 series connectors (CLAD42, CLAD62, CLAD62Z, CLAD72) provide direct functional equivalence to the JBXFD1G04MSSDSMR. All variants maintain identical electrical specifications: 4-position, male pins, solder cup termination, 10A current rating, gold-plated contacts, and UL94 V-0 flammability compliance. These parts are Active status and ROHS3 compliant. The primary differences are cable opening dimensions, which accommodate different wire gauges. Selection among these variants depends on the specific cable diameter requirements of the application.

Alternative Configuration (Mixed Pin Configuration):

The LEMO FFA.1S.304 series (CLAC52, CLAC62) offers 4-position connectors with female sockets and male pins in solder cup configuration. These parts maintain equivalent electrical performance and compliance ratings but feature a keyed orientation rather than the G orientation of the main part. These connectors are suitable for applications requiring mixed-gender pin configurations and are Active status with ROHS3 compliance.

Temperature Consideration:

All substitute parts operate across -55°C to 250°C, which exceeds the -40°C to 125°C range of the JBXFD1G04MSSDSMR. This extended temperature capability provides additional operational margin for applications within the original temperature specification.

Voltage Rating:

The main part specifies 900V voltage rating. Substitute parts from LEMO do not list voltage ratings in the provided specifications. Applications requiring explicit 900V rating confirmation should be evaluated against specific system requirements.

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.304.CLAD42 replace JBXFD1G04MSSDSMR directly?

A: Yes. Both connectors share identical electrical specifications: 4-position, male pins, solder cup termination, 10A current rating, gold-plated contacts, and UL94 V-0 compliance. The primary difference is cable opening dimension (0.122" ~ 0.165" for CLAD42 versus unspecified for JBXFD1G04MSSDSMR). Verify cable diameter compatibility before substitution.

Q: What is the difference between FGG.1B.304.CLAD62 and FGG.1B.304.CLAD62Z?

A: Both parts are electrically and mechanically identical 4-position male pin connectors with identical cable opening dimensions (0.205" ~ 0.244"). The designation difference reflects manufacturing or packaging variations. Both are Active status, ROHS3 compliant, and suitable for direct substitution.

Q: Can FFA.1S.304.CLAC52 be used as a substitute?

A: FFA.1S.304.CLAC52 is a 4-position connector with female sockets and male pins, differing from the JBXFD1G04MSSDSMR which has male pins only. This part is suitable only if the application requires mixed-gender pin configuration. The connector maintains equivalent electrical performance and compliance ratings.

Q: How do cable opening dimensions affect substitution?

A: Cable opening dimensions determine the wire gauge range that can be terminated in the solder cup. The JBXFD1G04MSSDSMR cable opening is not specified. Substitute parts offer different cable opening ranges: CLAD42 (0.122" ~ 0.165"), CLAD62/CLAD62Z/CLAD72 (0.205" ~ 0.244"), and FFA variants (0.165" ~ 0.205" or 0.224" ~ 0.244"). Select the substitute with cable opening matching your wire gauge requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH Unaffected, matching the regulatory status of the JBXFD1G04MSSDSMR.

Q: What is the difference between G orientation and Keyed orientation?

A: G orientation and Keyed orientation refer to connector alignment mechanisms. The JBXFD1G04MSSDSMR uses G orientation, while FFA.1S.304 series connectors use Keyed orientation. These are not interchangeable in applications requiring specific orientation control. Select substitutes with matching orientation for direct replacement.

Q: Do substitute parts support the same 900V voltage rating?

A: The LEMO substitute parts do not list voltage ratings in the provided specifications. The JBXFD1G04MSSDSMR is rated for 900V. Applications requiring explicit voltage rating confirmation should reference manufacturer datasheets or contact technical support.

Q: What is the inventory status of substitute parts?

A: All substitute parts are listed as Active status with available inventory: FGG.1B.304.CLAD42 (811 pcs), FGG.1B.304.CLAD62 (866 pcs), FGG.1B.304.CLAD62Z (1365 pcs), FGG.1B.304.CLAD72 (977 pcs), FFA.1S.304.CLAC52 (1093 pcs), and FFA.1S.304.CLAC62 (862 pcs).
